Description/Abstract

Despite the proliferation of materials in which waveguides may be formed, the vast majority of grating work is still carried out using silica-based optical fibres. This work is being driven by the fibre telecommunications and sensor markets, where there are requirements for low-loss, low-cost filters which are robust and easy to manufacture. There has yet to be serious interest in fibre gratings in other materials, although some devices are starting to appear. A full understanding of the underlying process to grating formation is not yet available.
